Abstract
An archery bow is provided having a cam assembly including a first bowstring track and a second bowstring track laterally separated by a distance, and adapted to guide different portions of a bowstring. The bowstring tracks can be spaced from one another along an axis of rotation of the cam assembly so that the loads exerted by the bowstring portions are substantially balanced. Accordingly, the loads are inhibited from urging the cam to lean out of vertical alignment and/or twisting the limb. The cam assembly can include a power cable track which guides a cable centered on the axis of rotation, and which is within a central longitudinal limb plane. Large, dynamic loads exerted by the power cable through the cam assembly can be centered to inhibit cam lean and limb torque. A related method of inhibiting limb twist, and a split bowstring also are provided.
